Al-Biruni
Abu Rayhan Muhammad ibn Ahmad al-Biruni (973 – after 1050) commonly known as al-Biruni, was a Khwarazmian Iranian in scholar and polymath during the Islamic Golden Age. He has been called variously the "founder of Indology", "Father of Comparative Religion", "Father of modern geodesy", and the first anthropologist. Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist, and linguist. He studied almost all the sciences of his day and was rewarded abundantly for his tireless research in many fields of knowledge. Royalty and other powerful elements in society funded Al-Biruni's research and sought him out with specific projects in mind. Influential in his own right, Al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he was conversant in Khwarezmian, Persian, Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Over time, they were under the suzerainty of the Sasanian Empire, the Hephthalite Empire, the Göktürk Khaganate, the Umayyad Caliphate, Abbasid Caliphate and the Samanid Empire. They were ultimately deposed by a rival family, the Ma'munids of Gurganj, who became the new rulers of Khwarazm. Sources Al-Biruni, the native Khwarezmian scholar, mentions twenty-two members of the Afrighid dynasty for a total span of 690 years with an average rule of 31 years for each ruler. According to him, the Afrighids ruled from 305, through the Arab conquests under Qutayba ibn Muslim in 712, and up to their overthrow in 995 by the rising rival family of Ma'munids. The main source on the Afrighids prior to Islam is also Al-Biruni. Part of the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Remaining Signs Of Past Centuries
''The Remaining Signs of Past Centuries'' ( ar, کتاب الآثار الباقية عن القرون الخالية ', also known as ''Chronology of Ancient Nations'' or ''Vestiges of the Past'', after the translation published by Eduard Sachau in 1879) by Abū Rayhān al-Bīrūnī, is a comparative study of calendars of different cultures and civilizations, interlaced with mathematical, astronomical, and historical information, exploring the customs and religions of different peoples. Completed in 1000 AD (AH 390/1), it is Al-Biruni's first major work, compiled in Gorgan, at the court of Qabus, when he was in his late twenties.Seyyed Hossein Nasr, ''An Introduction to Islamic Cosmological Doctrines'' (1993), , p. 108.

Islamic Golden Age
The Islamic Golden Age was a period of cultural, economic, and scientific flourishing in the history of Islam, traditionally dated from the 8th century to the 14th century. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom in Baghdad, the world's largest city by then, where Muslim scholars and polymaths from various parts of the world with different cultural backgrounds were mandated to gather and translate all of the known world's classical knowledge into Aramaic and Arabic. The period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the Siege of Baghdad in 1258. A few scholars date the end of the golden age around 1350 linking with the Timurid Renaissance, while several modern historians and scholars place the end of the Islamic Golden Age as late as the end of 15th to 16th centuries meeting with the I ...

Al-Sijzi
Abu Sa'id Ahmed ibn Mohammed ibn Abd al-Jalil al-Sijzi (c. 945 - c. 1020, also known as al-Sinjari and al-Sijazi; fa, ابوسعید سجزی; Al-Sijzi is short for "Al-Sijistani") was an Iranian Muslim astronomer, mathematician, and astrologer. He is notable for his correspondence with al-Biruni and for proposing that the Earth rotates around its axis in the 10th century. He dedicated work to 'Adud al-Daula, who was probably his patron, and to the prince of Balkh. He also worked in Shiraz making astronomical observations from 969 to 970. Mathematics Al-Sijzi studied intersections of conic sections and circles. He replaced the old kinematical trisection of an angle by a purely geometric solution (intersection of a circle and an equilateral hyperbola.) Earth's rotation Al-Biruni tells us that Al-Sijzi invented an astrolabe, called "al-zūraqī", whose design was based on the idea that the Earth rotates: Al-Biruni also referred to Al-Sijzi as a prominent astronomer who d ...

Anthropology
Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures, societies, and linguistics, in both the present and past, including past human species. Social anthropology studies patterns of behavior, while cultural anthropology studies cultural meaning, including norms and values. A portmanteau term sociocultural anthropology is commonly used today. Linguistic anthropology studies how language influences social life. Biological or physical anthropology studies the biological development of humans. Archaeological anthropology, often termed as 'anthropology of the past', studies human activity through investigation of physical evidence. It is considered a branch of anthropology in North America and Asia, while in Europe archaeology is viewed as a discipline in its own right or grouped under other related disciplines, such as history and palaeontology.

Islamic Philosophy
Islamic philosophy is philosophy that emerges from the Islamic tradition. Two terms traditionally used in the Islamic world are sometimes translated as philosophy—falsafa (literally: "philosophy"), which refers to philosophy as well as logic, mathematics, and physics; and Kalam (literally "speech"), which refers to a rationalist form of Scholastic Islamic theology which includes the schools of Maturidiyah, Ashaira and Mu'tazila. Early Islamic philosophy began with Al-Kindi in the 2nd century of the Islamic calendar (early 9th century CE) and ended with Averroes (Ibn Rushd) in the 6th century AH (late 12th century CE), broadly coinciding with the period known as the Golden Age of Islam. The death of Averroes effectively marked the end of a particular discipline of Islamic philosophy usually called the Peripatetic Islamic school, and philosophical activity declined significantly in Western Islamic countries such as Islamic Iberia and North Africa.

Ashari
Ashʿarī theology or Ashʿarism (; ar, الأشعرية: ) is one of the main Sunnī schools of Islamic theology, founded by the Muslim scholar, Shāfiʿī jurist, reformer, and scholastic theologian Abū al-Ḥasan al-Ashʿarī in the 9th–10th century. It established an orthodox guideline based on scriptural authority, rationality, and theological rationalism. Al-Ashʿarī established a middle way between the doctrines of the Aṯharī and Muʿtazila schools of Islamic theology, based both on reliance on the sacred scriptures of Islam and theological rationalism concerning the agency and attributes of God. Ashʿarism eventually became the predominant school of theological thought within Sunnī Islam, and is regarded as the single most important school of Islamic theology in the history of Islam. The disciples of the Ashʿarī school are known as Ashʿarites, and the school is also referred to as the Ashʿarite school, which became one of the dominant theological s ...

Circumference Of The Earth
Earth's circumference is the distance around Earth. Measured around the Equator, it is . Measured around the poles, the circumference is . Measurement of Earth's circumference has been important to navigation since ancient times. The first known scientific measurement and calculation was done by Eratosthenes, who achieved a great degree of precision in his computation. Treating the Earth as a sphere, its circumference would be its single most important measurement. Earth deviates from spherical by about 0.3%, as characterized by flattening. In modern times, Earth's circumference has been used to define fundamental units of measurement of length: the nautical mile in the seventeenth century and the metre in the eighteenth. Earth's polar circumference is very near to 21,600 nautical miles because the nautical mile was intended to express one minute of latitude (see meridian arc), which is 21,600 partitions of the polar circumference (that is 60 minutes × 360 degrees).
